The Alesis MULTIMIX 12R Rack Mountable 10-Channel, 12-Input Mixer is a high quality, rack mountable audio mixer designed for recording and sound reinforcement applications. The mixer features 8 mono inputs and 2 stereo paired (L/R) inputs, for a total of 12 line level inputs via balanced 1/4" TRS Phone connectors. Channels 1 through 8 feature XLR Balanced microphone inputs with phantom power (global switch). Each channel features a 2 band EQ (High / Low), 2 AUX sends and PAN (Balance control on stereo inputs). Additional I/O include L/R AUX returns, L/R Tape In and Tape Out jacks via RCA connectors, and L/R Main and Monitor outputs via balanced 1/4" TRS connectors. Channels 1 through 8 feature Inserts for direct routing of channels through out-board effects or signal processors using insert cables. The Insert points are also suitable for use as monitor sends (using tip-sleeve 1/4" cable only). All this enclosed in a convenient rack mountable enclosure provide sonic quality, durability while remaining portable.
Rack Mountable Enclosure
The mixer is enclosed in a 3-unit rack mountable enclosure making it a suitable road-worthy mixer for recording or sound reinforcement.
Mono & Stereo Channels
Channels 1 through 8 feature mono balanced 1/4" TRS inputs. The 2 remaining channels feature stereo paired (L/R) 1/4" TRS inputs, suitable for keyboards play-back devices and other stereo signals.
Balanced Mic Inputs
3-pin XLR female microphone inputs are featured on channels 1 through 8. All mic-preamps provide phantom power (global switched) for condenser microphones.
Channels 1 through 8 feature insert points for routing channels to effects or signal processors.
